Abstract: A wire theft deterrent system includes a first U-shaped portion and a second U-shaped portion for encapsulating wire in a riser that is associated with a telephone pole. The first and second U-shaped portions are both made of stainless steel, so as to be substantially resistant to saw blades and hammers. The first U-shaped portion and the second U-shaped portion are connected to one another by high-security fasteners, each of which passes through an aperture in a flange of the first U-shaped portion and a corresponding aperture in a flange of the second U-shaped portion. The high-security fasteners restrict access to the encapsulated wires, so as to deter wire theft.

Abstract: A method and system for providing Doppler data that is corrected for misalignment between the flow direction within a vessel and the beam orientation of the ultrasound probe. A conventional ultrasonic Doppler color mapping system is adapted to include a system to measure and record the free space position and orientation of the ultrasonic probe, as well as a system to generate and record the experiment time. A set of 2D image planes is acquired, each plane labelled with time, position, and orientation data. A structural representation according to the acquired data is used to determine the flow direction for the imaged vessel structure. Based on this identified flow direction, and the orientation and position information for each acquired 2D slice, the 2D Doppler signals are appropriately transformed into corrected velocity values. These corrected velocity values may then be used to construct a 3D flow field as a function of time.
